Anybody know how to disable the chicken bit on Windows?

They're not planning to fix this until fucking December...

It seems like there's an wrmsr (write MSR) tool for Windows [0]. I don't know whether it will work the same way as the linux verison.

That's atrocious. Looks like microsoft doesn't care about AMD CPU as much as AMD doesn't care about windows.

As far as I can see there is no easy way to use MSR on windows.

I may be missing something, but since it basically exploits AVX that is easy to disable in win10.

bcdedit /set xsavedisable 1

and then reboot.

At least it fails the zenbleed POC.
